A while ago, every time I started the LC there was a whistling noise; which always stopped after driving for a few minutes. At first I thought it was the V-belts, however, I checked these and all was okay.
It took me a while to figure out it was one of the bearings from the Alternator; this probably happened due to driving through deep water and mud whilst off-roading.
Luckily, I managed to source a 120amp for a decent price.
To get to the alternator this involves removing the air-box and the intercooler hoses due to the limited access.
There is 2 different plug style on the Alternator. This one is the oval type
Out with the “old” …….
…..in with the “new”
Make sure the plug fits
Hoses and air box refitted.
